How Long Is a Half Marathon?

A half-marathon distance is 13.1 miles (21.09 km) and is typically completed in 2 to 3 hours, depending on the runner’s ability level. It is an endurance race that has become increasingly popular among runners and aspiring athletes. While it may sound daunting initially, many runners find this distance achievable and rewarding with training and preparation.

Let’s take a closer look at what it takes to run a successful half-marathon. 

Training for a Half-Marathon 

To complete a half-marathon, you’ll need to have a specific training plan in place beforehand. Begin by running shorter distances, like 5Ks or 10Ks, as part of your regular training program. This will help you build up your endurance and increase your confidence before race day so you can finish strong.

Once you have built the necessary strength and endurance, slowly work your way up to longer distances until you are ready to tackle the full 13 miles. It’s also important to keep your body hydrated while running, especially during longer distances like the half-marathon.

Ensure you drink plenty of water before, during, and after each run—even if it’s cold outside—to stay hydrated. Make sure to eat healthy snacks throughout the day to maintain energy levels for your runs. 

Race Day Preparation 

On race day, arrive early enough so you have plenty of time for warmups and stretching before the starting gun goes off. This will ensure that your body is appropriately prepared for the long distance ahead.

Also, remember to wear comfortable clothes that won’t restrict movement or cause discomfort during the run; lightweight shorts or sweatpants, a t-shirt, or a tank top should do just fine. Finally, don’t forget to bring an ID and other items like energy gels or energy bars so you can refuel during the run as needed.

Is a Half Marathon Good For Beginners?

A half marathon is a great goal for beginner runners. It’s a distance that is challenging but doable, and it will give you a sense of accomplishment when you finish. Training for the race can also help you lose weight, get in shape, and improve your overall health.

Tips For Beginners

Get a Good Pair of Shoes: This may seem obvious, but it’s important to ensure that you have a good pair of running shoes that fit well and offer support. Nothing is worse than having blisters or other foot issues during a race.

Build Up Your Mileage Gradually: Don’t try to do too much too soon. When starting, focus on running a few miles a week and gradually increasing your mileage each week.

Incorporate Cross-Training: In addition to running, make sure to add other forms of exercise such as biking, swimming, or strength training. This will help improve your fitness and make you a better runner.

Create a Race Plan: Once you have registered for the race, it’s important to start thinking about your race strategy. Decide what pace you want to run at and break down the miles into manageable chunks. This will help keep you on track during the race.

Stay Motivated: Training for a half marathon can be tough, so finding ways to stay motivated is important. Set goals for yourself and reward yourself for reaching them. Connect with other runners who are training for the same race. They can offer support and encouragement.

Will Running a Half Marathon Help Me Train For a Full Marathon?

A half marathon can help prepare you for a full marathon. In fact, many runners use the half marathon distance as a key training component in their full marathon build-ups. Why? Because the half marathon is long enough to provide a significant endurance challenge but not so long that it requires excessive time and energy to recover from.


Half marathons are becoming increasingly popular among runners of all experience levels looking for an exciting challenge and an opportunity for self-improvement and personal growth.

Knowing how far a half marathon is—13 miles (21 km)—and knowing what it takes to adequately prepare for such an event can give aspiring athletes more confidence when they take on this exciting challenge. With proper preparation and dedication, anyone can become ready to tackle their personal best in their next half marathon.
